Title: Positive-locking connection
Inventor: TRAEGER WALTER DIPL ING
IPC: A47B57/40
Filed: 1985-09-21
Abstract: The invention relates to a positive-locking connection of two beams, in particular for use in frame-like constructions. The intention was to find a constructional solution for a connection, which is distinguished by improved positive locking. The object was achieved by the fact that the one beam 1 has, in a known manner, perforations 2 and the second beam 3 is connected, in a manner resistant to bending, to an angle section 4, the perforations 5 of which are congruent with the perforations 2 of the beam 1 to be connected. The two beams 1; 3 are connected by means of a plate-shaped element 6, the hooks 7 of which engage positively in the congruent perforations 2; 5 of the beams 1; 3. Advantageously, these hooks 7 exhibit a certain inclination 8 and the number of perforations 2, 5 and hooks 7 is set according to the particular load. <IMAGE>

Title: Self-commutated invertor having an impressed current
Inventor: STILL LUDWIG DIPL ING
IPC: H02M7/515
Filed: 1985-10-17
Abstract: In the case of this invertor which is connected to a DC intermediate circuit and is wired up to an asynchronous machine (AM), a thyristor bridge, which consists of six main thyristors (T1... T6), and a parallel path for turning the main thyristors off are provided. The parallel path consists of an upper half-controlled two-phase bridge which is connected to the positive current output (A) of the intermediate circuit, of a six-pulse diode bridge (D1... D6) which is connected in series therewith on the DC side, and of a lower half-controlled two-phase bridge, which is connected downstream therefrom on the DC side and is connected to the negative current output (H) of the intermediate circuit. The diode bridge is connected to the thyristor bridge on the AC voltage side. The half-controlled two-phase bridges have two GTO thyristors (GTO1...GTO4) and two diodes (DO1, DO2, DU1, DU2). Reactive volt-ampere capacitors (CU, CO) are connected between the AC voltage terminals of the half-controlled two-phase bridges. The use of the GTO turn-off path results in a reduction in the volume to weight ratio of the invertor. Furthermore, the invertor is largely independent of the machine and its load state. A possibility for use exists in the case of drives for vehicles on rails, and industrial installations. <IMAGE>

Title: Oil filter with main and secondary flow
Inventor: BAUMANN DIETER DIPL ING
IPC: B01D27/14
Filed: 1987-02-13
Abstract: In known oil filters of the type stated under point 1, relatively large hollow spaces exist inside the filter housing in addition to two filter elements, which spaces contribute nothing to the function of the filter. The new oil filter is intended to be more compact for the same performance or to afford a higher rate of flow and/or longer service lives for the same overall dimensions. In order to obtain an improved utilisation of the space in the new filter, it is proposed that the two filter elements (3, 4) be arranged coaxially with one another, at least over a part of their length, forming an intermediate gap (22). The oil filter is suitable for all types of internal combustion engines with circulating oil lubrication. <IMAGE>

Title: Refuse bin opener with foot operation
Inventor: DOERR WILHELM ING GRAD
IPC: B65F1/16
Filed: 1987-08-27
Abstract: My Patent No. 3313309.3 and my Patent Application No. 3700264. These patents use the lid handles to open the lid and are also dependent on the type of bin handles. Both bin and lid handles have complicated the designs and increased production costs because of their many shapes. Another approach has therefore been sought and found. The results are:     1) The lid handles no longer play any part.   2) The bin handles no longer play any major part.   3) The lid is raised on the lid arm.   4) The angle of opening is larger (60@).   5) The new opener is lighter (3000 grams).   6) It is easier to produce.   7) It is cheaper to produce.   The apparatus is suspended unchanged on the bin in a bin handle, and the lid arm is inserted by lifting the lid by hand, the lid being let down into the U-shaped stirrup (14). When the foot pedal is operated the lid is raised on the lid arm via a lever arm and a lifting rod with an articulated U-shaped stirrup (14). When the foot is removed, the lid closes as a result of its own weight. <IMAGE>

Title: Method for monitoring the reliable mode of operation and for the early detection of damage in complicated technical systems
Inventor: SUNDER REINHOLD DIPL ING
IPC: G21C17/00
Filed: 1987-10-12
Abstract: With the aim of increased operational reliability and an economically improved mode of operation by means of an early detection of damage which offers more effective prevention in the case of complicated technical systems, a monitoring arrangement and a monitoring method are proposed with reference to the example of a nuclear power station. In this case, measured vibration data are determined using various sensors. The signals determined for the individual measurements points are decomposed in their spectrum of vibration frequencies, from this there are determined and selected frequency ranges and/or combinations which are determined from the frequency spectrum thus resolved and are specifically relevant to a state response or perturbation response of the individual structural components, and changes in these spectral frequency ranges are compared with respect both to their frequency value and to their amplitude and/or discriminant (e.g. in the form of a measure of similarity, possibly mathematically formulated, of the frequency distribution) with reference characteristics which are to be assigned in a predetermined fashion and are processed to form a signal specific to the monitoring. <IMAGE>

Title: Method for binding pollutants and absorbent for pollutants
Inventor: HOELSCHER RICHARD DIPL ING
IPC: C02F1/28
Filed: 1988-01-14
Abstract: In a method for binding pollutants, in particular free-flowing pollutants, especially liquid pollutants and pollutants entrained in free-flowing media, porous minerals such as chalk, but in particular chalk made hydrophobic or other hydrophobic materials are used, that is in very fine to medium grain, as collecting and support material for pollutants, such as hydrocarbons. It has been shown that chalk, in particular hydrophobic chalk, has a high absorption capacity for free-flowing, in particular liquid, pollutants. Therefore, it is particularly useful for the production of absorptive layers which are used, for example, as lower layers, intermediate layers or covering layers of contaminated soils.
